Hi Andrea,

P2P is an optional specification from PCIe spec, and the IP is not developed with the consideration to support P2P. Thus, the IP does not claim that it can support P2P. And we never test the P2P using the IP. Thus, I can’t help much on this.

But just for sharing, I try to check the PCIe specification 3.0. Looks like to achieve P2P, we will need to trigger from the rp which is the host. From ep perspective, it is passive and just to ensure that it can send out the packet correctly with targeted address.
